Changing the focus of your city.

[KrikkitTwo]

Imagine what you want, but I think it's probably simpler to think of cities as large urban areas. That could be cities and the surrounding countryside, cities and their suburbs, megalopolises, etc. (depending on the time period and city size). There just seems to be more parallels to the real world than imagining a city is "California" with the city center being way off in Sacramento while all of LA is just a district.

Actually, it makes sense if the LA area is several districts close together. (Or California is 2 cities, Sacramento cc for North (with SF as the Harbor, Science, Commercial District cluster), LA for South

I once nuked my own subjects hard enough to trigger a fast golden age to solve my economic problems.

You, sir, I now regard as cold hearted b---- #1. I thought a few of those guys down in the Civ III subsection couldn't be topped (see my third quote).

It's known that the world wonders can't be destroyed;

I think they should give you the opportunity to destroy wonders for some financial return if you sack a city (you could incur a diplomatic penalty though).

Think about it - The only one of the seven ancient wonders to survive is the Pyramids - and muslim fanatics even tried to destroy that - except it proved to difficult a task.

Many wonders have been destroyed by natural events or by wars. I think its a bit odd that Stonehenge is still producing faith in the modern era. Perhaps ancient/classical era wonders should crumble over time and be replaced with an archaeology site so you can generate tourism from them.

The only video evidence regarding the state of district placement in regards to new districts is that districts and wonders can be placed on top of existing improvements, but not on existing districts.

There is also the video for the event where some people played the first 60 turns. Interesting to note that on that video, the campus was show to be buildable over deer and stone, but not over cotton. So maybe only strategic and luxury resources don't let you build district on top, while you can on top of bonus resources. The question Pete answered was about a strategic one, I believe.
